Hi Jim,
I debugged the code for you, looks like i'd missed quotes around the command in code i'd previously posted:
#'------------------------------------------------------------------------------
#'Enumerate the UNIX user mapping for the server.
#'------------------------------------------------------------------------------
[String]$command = Get-NcNameMappingUnixUser -Name $UnixServer -VserverContext $VServerName -ErrorAction Stop
Here is example output of how i tested it externally to WFA in my lab using a powershell script.
PS C:\> cd C:\Scripts\PowerShell\Projects\WFA\SetUserMapping
PS C:\Scripts\PowerShell\Projects\WFA\SetUserMapping> .\SetUserMapping.ps1 -Cluster cluster1 -VserverName vserver2 -UnixServer LINUX01
Enumerated WFA installation Path from Registry key "hklm:\system\currentcontrolset\services\na_wfa_srv" as "C:\Program Files\NetApp\WFA"
Loading WFA profile
Executed Command: Connect-NcController -Name cluster1 -HTTPS -Credential $credentials -ErrorAction Stop
Connected to cluster "cluster1"
Executed Command: Get-NcNameMappingUnixUser -Name LINUX01$ -VserverContext vserver2 -ErrorAction Stop
Enumerated UNIX user mapping for server "LINUX01$" on vserver "vserver2"
Executed Command: Get-NcNameMappingUnixUser -Name L* -VserverContext vserver2 -ErrorAction Stop
Enumerated UNIX user mapping for server "L*" on vserver "vserver2"
UserName UserId GroupId Vserver FullName
-------- ------ ------- ------- --------
LINUX01$ 10000 65534 vserver2
Executed Command: New-NcNameMappingUnixUser -Name LINUX01$ -UserId 10000 -GroupId 65534 -VserverContext vserver2 -ErrorAction Stop
Created user mapping for server "LINUX01$" UserID "10000" GroupID "65534" on vserver "vserver2"
PS C:\Scripts\PowerShell\Projects\WFA\SetUserMapping>
I tested it a few times just to make sure it increments the UserID for the host by incrementing 10K + 1. Works fine. Here is the source code for the above script:

I am familiar with the WFA Guy Blog. I attended one of his session at Insight in Las Vegas last month, and it was fantastic. I have been trying to get time to go through more of the blog, but have been struggling with this instead.
